Nexgard flea meds cause my dog to get very sick. She does not know where she is and starts to get pancreatitis again. Are there any safer alternative?

Hello, so sorry to hear that Kya had this problem with the Nexgard. Personally, if my dog had a reaction to one of the oral flea medications (like Nexgard) I would not using any oral products in the future. I suggest you switch to a Seresto Collar. ( https://www.petco.com/shop/en/petcostore/product/seresto-flea-and-tick-collar-for-dogs ) One collar lasts 6-8 months depending on how much swimming/bathing the dogs does. I think you will be happier (as will Kya) with this collar. It is almost less expensive than using a monthly prevention. Hope this helps. Best wishes.
